The random image is generated by the following statement on my main page:
<?php include('random.image.php'); ?>
Below is the listing for the file 'random.image.php'. The script uses a text file called 'images.inline.txt' which contains one line of HTML code for each image. Basically, the PHP script substitutes an HTML <IMG> for itself.
When the script DOESN'T WORK, no HTML is substituted into the main page, and therefore I get no image.
